It's very hard to say. Do you have any idea how old they were before they were shipped? Eggs can stay viable for up to 3 weeks, but that's pushing it hard. I wouldn't recommend incubating eggs older than 2 weeks, max, but since you paid for these I'd say give it a shot and Remember when you get them to place them upright in a cool place (65*F or thereabouts) for 24 hours to let them settle before setting them. Good luck!

i had 6 eggs at around 75 degrees for a week. then i tried to incubator them .after a week they all had blood rings and were no good.hope you have bettetr luck.best to find a local place i think. never trust the usps,ups or fedex

Fertiized eggs should be stored at roughly 60 degrees. 75 is too hot. A basement is a great place to store eggs until they are ready to go into the incubator. Holding them no longer than a week is best. 2 weeks at MOST
